“…Therefore, the validity of these methods to deal with GRC lacks theoretical support. Towards LFC design with GRC, the extended integral control method in [26], the biased PI dual mode control method in [27], the Type-2 fuzzy approach in [28], and the anti-GRC PI-type controller in [29,30] are adopted to deal with the GRC problem. Unfortunately, the strict mathematical proof in the above methods is still absent.…”

Abstract:To deal with the problem of generation rate constraint (GRC) during load frequency control (LFC) design for a multi-area interconnected power system, this paper proposes an anti-windup controller design method. Firstly, an H ∞ dynamic controller is designed to obtain robust performance of the closed-loop control system in the absence of the GRC. Then, an anti-windup compensator (AWC) is formulated to restrict the magnitude and rate of the control input (namely power increment) in the prescribed ranges so that the operation of generation unit does not exceed the physical constraints. Finally, the anti-windup LFC is tested on the multi-area interconnected power systems, and the simulation results illustrate the effectiveness of the proposed LFC design method with GRC.

“…The closed‐loop control system along with the PSS/TCSC controller is equated with the reference model in frequency domain and the analytical controller is derived therefrom. From this ideal controller, the PSS/TCSC controller is approximated using the concept of low frequency response matching as in Anwar and Pan . However, in Anwar and Pan two low frequency points are used for the design of PID controller whereas only one frequency point is sufficient here for the design of the proposed controllers.…”

Summary For improvement of the operation and control of the power system, the flexible AC transmission system devices are significantly used. This paper proposes a model‐based frequency response matching technique for designing a lead‐lag power system stabilizer and a thyristor controlled series capacitor controller to improve the small signal stability. The method relies on development of an appropriate reference model, based on the desired specifications that can be attainable by the system dynamics. The unknown controller parameters are obtained by the frequency response matching between the closed‐loop control system and the reference model. The efficacy of the proposed controllers is examined on an unstable test power system taken from the literature. Improvement of the damping factor and the other performance indices shows robustness and effectiveness of the proposed controllers for stabilizing the power system oscillations in comparison with some design methods prevalent in the literature. It is illustrated through rigorous simulation that the proposed controller works successfully for stabilizing the power system over a wide unstable operating conditions and perturbed system models.

“…Recently, Padhan and Majhi [37] tuned a PID controller using Laurent series expansion, and extended the approach to a multiarea case by performing robustness analysis. Subsequently, Anwar and Pan [38] introduced a direct synthesis approach for PID controller design through frequency response matching. Further, a fractional order PID controller [30,32] is designed for a single area power system, which provides robustness towards parameter uncertainties and disturbance rejection.…”

Abstract:In this paper, we propose a modified two degree-of-freedom internal model control structure, with dual feedback loop configuration for the load frequency control problem of a single-area power system. Our main objective is to achieve better transient and steady state performance. The predictive model of the proposed configuration is derived through the stability equation method, which preserves the stability of the model. The proposed scheme is simulated for a single-area power system with nonreheated turbine and 50% parametric uncertainty. It is observed from the responses and the performance indices that the proposed control configuration gives better results compared to well-known existing techniques.
